Well ... it seems an apology is in order, for my post regarding Mirror's Edge: it turns out that the many many problems I've had with the game came not from EA's developers, neither testing nor bad karma, but from Windows Vista.
The game should not have had BETA plastered over it, just a disclaimer:
"This game is only partially working with Windows Vista. Use at your own risk."
I installed XP (details to come in a future post) and finished the game through the weekend. It was nice (though a bit shorter than I expected).
